Once you pressed the expanded part on the pen, it took a minute for the fluid to reach the tip of the pen. While pressing the pen, I was able to add the fluid to my paper in a neat manner. I like it better than the correction tape as it allows you to correct smaller areas.

I ordered this product a week ago thinking this would work out better since it is skinny and you can go over exact lines. However, I have been unable to get the thing to work. I squeeze and squeeze and nothing ever comes out. I am not sure if the inside is dried up or I just got a bad pen.
